Key capabilities
What sets it apart
Unified pipeline. Text-to-video and image-to-video run through the same model — no separate specialized versions. Upload an image to animate it, or describe a scene from scratch to generate it.
Joint audio-video generation. HappyHorse generates dialogue, ambient sound, and Foley effects alongside the video in a single pass rather than adding audio as a post-processing step. The result is naturally synchronized audio-visual output.
Multilingual lip-sync. Native lip-sync support for English, Mandarin, Cantonese, Japanese, Korean, German, and French — opening the model to global content creators without dubbing tools.
Fast distilled inference. An 8-step DMD-2 distillation process reduces denoising steps significantly, enabling competitive generation speeds at 15B parameter scale.
